Here is Alvin Plantinga's review of Thomas Nagel's new book, Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False. Both Plantinga and Nagel are moral objectivists. Both reject naturalism. They differ in that Plantinga is a theist and Nagel an atheist.
Another similarity between the two philosophers (among the most eminent in the discipline) is that both are grown-ups. Both are committed to following reason where it leads; both are respectful of those with whom they disagree; and both believe that science and metaphysics (the latter, but not the former, a branch of philosophy) are distinct. The best part of the review is Plantinga's final sentence. He says that, "wherever he [Nagel] winds up [with theism or atheism], he has already performed an important service with his withering critical examination of some of the most common and oppressive dogmas of our age."
That is what infuriates the likes of Brian Leiter and Michael Weisberg: Nagel thinks for himself. The academic tribe does not take kindly to freethinkers. Either you're a member of the tribe, committed to its beliefs, values, and practices, or you're an outsider. (This is particularly true in ethics, broadly construed to include political philosophy.) It would be funny if it weren't so sad. Of all places, academia is supposed to be a place for open-minded inquiry. It should celebrate, not castigate, independent thought. It should welcome, not exclude, iconoclasts, dissidents, outsiders, heretics, and freethinkers. One can only hope that Nagel inspires a new generation of philosophers to reject the dogmatism of Leiter et al. It's time for skeptics to reclaim academia.
